"Namespace not defined" with 1.3+ version for Flutter Android

[erenardi]

Got the following error message using the latest version

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring project ':dynamsoft_capture_vision_flutter'.
> Could not create an instance of type com.android.build.api.variant.impl.LibraryVariantBuilderImpl.
   > Namespace not specified. Specify a namespace in the module's build file. See https://d.android.com/r/tools/upgrade-assistant/set-namespace for information about setting the namespace.

     If you've specified the package attribute in the source AndroidManifest.xml, you can use the AGP Upgrade Assistant to migrate to the namespace value in the build file. Refer to https://d.android.com/r/tools/upgrade-assistant/agp-upgrade-assistant for general information about using the AGP Upgrade Assistant.

Error: Gradle task assembleDebug failed with exit code 1

Steps to reproduce:

1. Create basic Flutter app
2. Modify the following in the main()

void main() async {
  WidgetsFlutterBinding.ensureInitialized();

  // Put your Dynamsoft Barcode Reader license here.
  // Initialize license for the Barcode Decoding module of Dynamsoft Capture Vision.
  // The license string here is a time-limited trial license. Note that network connection is required for this license to work.
  // You can also request an extension for your trial license via the Request a Trial License link: https://www.dynamsoft.com/customer/license/trialLicense?product=dbr&utm_source=github&package=flutter&version=9
  const String licenseKey =
      'DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9';

  // Initialize the license so that you can use full feature of the Barcode Reader module.
  try {
    await DCVBarcodeReader.initLicense(licenseKey);
  } catch (e) {
    print(e);
  }

  runApp(const MyApp());
}

3. Run the app with Android emulator.

The initialization works for iOS emulator, but not Android emulator
